Re: [PATCH v7,0/2] media: mediatek: vcodec: add hevc stateless decoder driver in MT8195

["Yunfei Dong (董云飞)" <Yunfei.Dong@mediatek.com>]

Hi Hans,

Thanks for your suggestion.

I don't understand your means very well, need to confirm with you
again.

hevc(v7) --- > media: mediatek: vcodec: support stateless hevc decoder
plt(v3)  ----> media: mediatek: vcodec: Fix decoder under flow and plt
test fails randomly

Whether hevc and plt patches merged together?

Whether you mean I need to post v8 for hevc patch based on plt patch as
below order?
hevc(v7)
plt(v3)
media stage HEAD

I cherry pick all patches, won't get conflict.

Or I need to post hevc patch based on media stage HEAD?
hevc(v7)
media stage HEAD

Best Regards,
Yunfei Dong
